Title: Method and apparatus for control of pwm flow rate
Inventor: NAKAYAMA TETSUYA
IPC: G05B11/28
Filed: 1979-08-29
Abstract: PURPOSE: To enhance the linearity of the control appratus, by flowing a large amount of driving current to the solenoid when the electromagnetic valve is on and thus securing a quick on-state for the electromagnetic valve.  
     CONSTITUTION: The on- and off controls are given alternately to the electromagnetic valve to give a control to the mean flow rate of the liquid. In this case, a large amount of driving current is flowed to the solenoid of the electromagnetic valve during a comparatively short time τON from the start point of the on-time tON of the electromagnetic valve. Thus the spool of the electromagnetic valve is turned on quickly. After this, a comparatively small amount of holding current is supplied to maintain the shift of the spool. Thus the time τON required for the on of the electromagnetic valve is reduced to reduce also the error of linearity.

Title: Editing device, data recording and reproducing device, and method for recording subject matter to be edited
Inventor: MORISHIMA SHINICHI
IPC: H04N5/91
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of editorial work carried out by means of a video server. SOLUTION: An A/V(audio/video) server makes a VTR(video tape recorder) reproduce subject matter data by queuing up the VTR to a pre-rolling point and, after a preset prescribed period of time has elapsed from the pre-rolling point, starts to record the subject matter data in a HDD(hard disk drive). The recording of the data is started before an IN point is reached after the VTR starts the reproduction and the reproduction output of the VTR is stabilized. Thereafter, the A/V server stops the data recording when a preset prescribed period of time has elapsed after the OUT point of the data is reached and stops the data reproduction by means of the VTR before the data reach a post-rolling point.  When the A/V sever again performs access to the vicinity of the same subject matter data as those recorded on the VTR, the server does not perform access to the VTR, but to the data recorded in the HDD.
